[Bug] Ardwen's Gloves + Stone Wall

https://github.com/flareteam/flare-game/issues/802

I can confirm that this bug occurs (version 1.09.01).

I havent understood the bug yet,
it behaves crazily.

It occurs for some combinations of
- character level
- stone-wall level
when ardwen's gloves are equipped,
and then disappears and reappears when the character increases
the character level and/or the stone-wall level.

The numbers in the HP-bar flicker,
HP regeneration is stuck or even goes in the negative direction,
and in the list of character status values
the numbers for only the following 3 entries flicker:
- Max HP
- Absorb Min
- Absorb Max

These are exactly the quantities affected by the stone-wall skill.

In order to reproduce the bug,
create a character at level 1, with the power 37 (stone-wall lvl 1),
have offense,defense >= 3 to equip the gloves,
equip the gloves (item 92)
and the flickering will occur.

for the below save -- as far as i can see that --
the flickering is between two values
(without gloves / two values with gloves)
- Max HP : 225 / 200 250
- Absorb Min: 5 / 3 9
- Absorb Max: 5 / 4 10 or 1 40
